Analysis of rolling process principle of color steel tile press

One of the basic principles of cold bending forming process of color steel tile equipment is that the strip is bent along the longitudinal direction in a straight line. However, the combination of the pressure generated in the process of bending deformation and the residual stress in the strip often makes the strip deviate from the cold bending equipment. The most commonly used words to describe the deviation of the strip from the last forming roll are: side bending - horizontal bending, warping - vertical bending, twisting - spiral. In order to solve this problem, the straightening mechanism should be used at the end of the cold bending machine. The basic principle of straightening mechanism is that for the profile with side bending, warping and other defects, the straightening mechanism should have enough pressure along the opposite direction to produce permanent deformation. If the deformation along the opposite direction is appropriate, the profile can be completely straightened after springback.

If the profile is distorted in a certain direction during the forming of color steel tile press, the straightening mechanism will rotate the profile in the opposite direction in order to produce permanent plastic deformation. If the rotation angle is appropriate, the profile will not twist after springback.
